Unable to connect with Loki. Please check the server logs for more det

Hi everyone,

I’m currently trying to set up the Loki plugin via Grafana but I always get the error message “Unable to connect with Loki. Please check the server logs for more details” when I want to add the data source in Grafana. I have Grafana and Loki installed on an Unbuntu server. I followed these instructions. Local | Grafana Loki documentation

The ports are of course all unlocked

hi there,

Is there any output/logs from Loki server? Does Grafana run on the same server as Loki? Is port 3100 open in your firewall?
